Letters Patent No. 88,069, dated March 23, 1869.

ILEPROVEMET IN WATER-ELEVATOR.

'To all whom it may concern: Y

Beit known that I, G. D. PALMITER, of the city and county of Oswego, andState of New York, have invented a new, improved, and useful Machine forElevating Water, known as a Water-Elevator, being an improvement (newand useful) upon all other waterelevators heretofore known or used; andI do hereby declare that the following is a full, clear, and exactdescription of the construction and operation'of the same, referencebeing had to the annexed drawings, making apart of this specification,in which- Figure 1 is a front elevation of the entire waterelevator.

Figure 2 is a section of the drum, shaft, frictions, spiralrecess in onepart of the frictions, stud, or projection on the shaft, ,fitting intothe spiral recess, and spring connected with the cap-piece of thefriction pieces, and to the handle by which the drum is revolvecl.

Figure 3 is a view of the shaft which .runs throng the drum, with thestud, or projection, which fits into the spiral recess of the frictioncap-piece.

Y Figure 4 'is a section of the same shaft,with the same studprojecting.

'Figure 5 is a section of the cap-piece of the frictions, showing theentrance to the spiral recess in that part of the friction.

Figure 6 is an end view of the same cap-piece, showing the ratchet, onthat piece, to receive the pawl, which is fastened to the curb.

Like letters refer to like parts in the drawing.

t' is the shaft, on which the drum g and friction d revolve, when loose,and with and by which they (both drum and friction-piece d) are revolvedwhen fast.

b represents the ratchet upon which the pawl c acts.

f, the crank, and v A`c, the spring, which is attached to the cap a, at'one end, and the crank fat the other.

a represents the cap-piece of the friction, and d, the other partthereof.

g represents a drum, on which the strap, or a cord or chain, h, iswound, by turning the crank f, when the drum is made fast by thefriction-pieces a and d.

j represents the stud, or projection, on the shaft t, which fits intothe spiral recess, or slot, k, in the cappieee a of the friction-pieces.

To operate this water-elevator, a bucket is attached to the strap h, ora rope or chain instead, and, being in the well, or cistern, the bucketbeing full of water, the crank f is turned in the natural direction toturn a. crank, (over and from you,) the stud, or projection,

j, on the shaft t', (which may be a stud simply, or shaped like aportion of the thread of a coarse screw,) will move with the shaftforward in the spiral recess 15 (whichrecess Vmay be, instead, a slot,cut spirally clear through the sleeve of the cap-piece a of thefrietion,) and, moving-forward, it will force the cap-piece against andupon the other part of the friction, at x, with great power, theleverage of the crank and incline, or pitch, of the spiral recess, orslot, making it a combination of the lever and inclined plane, while theshape of the flange x, on the cap-piece a, and the other part ofthefriction d, at x, forms another inclined plane, and again multiplies theforce applied to the crank. The stud on the shaft," being a part of theshaft, will carry with it the friction-cap a, which, being thus forcedon to the friction-piece d, will carry that'with it, and,'asthe'friction-piece d is fast to and forms one end'of the drum g, thedrum will be revolved, and will wind np the strap h, and raise thebucket of water attached to it, when, the bucket being emptied, weproceed to lower the bucket again. This is done by reversing thepressure on the crank, when the pawl c catches on the ratchet b, on thesleeve of the friction-cap a, and prevents its turning back, while thestud j is forced, by the backward motion of the crank-shaft, backward inthe spiral recess, or slot k, and will thus draw the cap-piece a awayfrom the fn'ction d, thus leaving the drum g, which is loose on thecrank-shaft, free to revolve loosely, and the'bucket will descend by itsown weight.

If it should be wished to stop the bucket in its descent, it is onlynecessary to let go ofthe crank, and the spring e will move the crank,in the same direction as it was turned to elevate the bucket, far enoughto again force the cap-piece on to the friction d, and the drum g willbecome fixed, and held by the action of .tne pawl c and ratchet b, andthe bucket will be arrested, in its descent, at that point, and will soremain until,l by turning the crank forward, it will be again raised,or, by pressing the `crank back, the drum will be released, and descendto the water.

I disclaim all other parts of the said described waterelevator, as theyare not new, but in common use.

What I claim as my invention, and desire to secure byLetters Patent, is-

The combination l:of the friction-pieces a and d, the

stud j, spiral recess, or slot k, and spring e, arranged'- snbstantiallyas shown and described. v
